Abstract

Two beams of a railway car retarder which are located on opposite sides of a track rail are provided with brake shoes in the form of segments. The segments are positioned in recesses on the inside longitudinal sides of the beams. The recesses are separated from one another by web ribs. The segments are form-closed with the longitudinal recesses of the beams and fixedly located therein. By means of this braking system the squeaking sounds arising during the braking operation are substantially reduced.

Description

Die Erfindung betrifft eine Balkengleisbremse aus jeweils zwei beidseitig jeder Fahrschiene einer Gleise liegenden, oder aus nur zwei beidseitig einer Fahrschiene liegenden, parallel zu derselben verlaufenden Balken mit nebeneinander gereihten Segmenten als Brembeläge, die zwischen sich eine für die abzubremsbeläge, die zwischen sich eine für die abzubremsenden Räder eines sich bewegenden Eisenbahnwagens bestimmte Bremsrille bilden, wobei die jeder bzw. der Fahrschiene zugekehrten Längsseiten der Balken längliche Aussparungen aufweisen.The invention relates to a bar track brake consisting of two bars on both sides of each track of a track, or from only two bars on both sides of a track, running parallel to the same with bars arranged next to each other as brake pads, the one between them for the brake pads, the one between them for the to be braked wheels of a moving railroad car form certain braking groove, the longitudinal sides of the beams facing each or the rail having elongated recesses.

Die Balkengleisbremsen dieser Art haben die Aufgaben, die in einem Rangierbahnhoft ablaufenden Eisenbahnwagen auf eine bestimmte Geschwindigkeit abzubremsen oder sie ganz zum Stehen zu bringen. Bei der Bremsung werden die Wagenräder von je zwei Balken der Gleisbremse, die aus ihren Ausgangsstellungen angehoben werden, seitlich angepresst. Beim Bremsvorgang entstehen schrille, quitschende Geräusche von erheblicher Lautstärke. Diese Geräusche entstehen durch Schwingungen der Wagenräder infolge der Reibung zwischen den Bremsbelägen der Bremsbalken und den Wagenrädern. Solche Geräusche sind für die Umwelt belästigend.The beam track brakes of this type have the task of braking the railway carriages running in a marshalling yard to a certain speed or of bringing them to a complete stop. During braking, the wagon wheels are pressed laterally by two bars of the track brake, which are raised from their starting positions. The braking process produces shrill, squeaky noises of considerable volume. These noises are caused by vibrations of the wagon wheels due to the friction between the brake pads of the brake beam and the wagon wheels. Such noises are a nuisance to the environment.

Verschiedene Mittel wurden angewandt, um das beim Bremsen entstehende Geräusch mindestens zu vermindern. So wurden die Kontaktflächen zwischen den Bremsbelägen und den Wagenrädern mit flüssigen oder halbflüssigen Bremsmitteln aus Trägerflüssigkeit und körnigem Bremsmaterial bespritzt. Es wurde auch versucht, die Reibflächen mit wässerigen Pasten, Oel/Wasseremulsionen oder flüssigem Schaumstoff zu belegen, welche Mittel aber verhältnismässig geringe Resultate brachten und ausserden kostspielig waren, weil sie in grossen Mengen zum Einsatz kamen.Various means have been used to at least reduce the noise generated when braking. For example, the contact surfaces between the brake pads and the vehicle wheels were sprayed with liquid or semi-liquid braking agents made from carrier fluid and granular brake material. Attempts have also been made to cover the friction surfaces with aqueous pastes, oil / water emulsions or liquid foam prove which means brought relatively small results and were also expensive because they were used in large quantities.

Gemäss der deutschen Patentschrift Nr. 2 254 005 werden die Schwingungen der Wagenräder beim Bremsvorgang durch eine neben der Fahrschiene angeordnete und an die Wagenräder bei deren Durchlauf angreifende Schiene aus gummielastischem Material aufgefangen. Somit werden die beim Bremsen auftretenden Quietschgeräusche unterdrückt.According to German patent specification No. 2 254 005, the vibrations of the wagon wheels during the braking process are absorbed by a rail made of rubber-elastic material which is arranged next to the running rail and engages the wagon wheels during their passage. The squeaking noises that occur when braking are thus suppressed.

Obschon die Wagenräder die gummielastische Schiene nur schwach berühren, wird sie doch beim Befahren insbesondere durch Lokomotiven oder ganze Züge mit der Zeit zerstört. Ausserdem ist die Beschaffung und Installierung solcher zusätzlicher gummielastischer Schienen kostspielig.Although the wagon wheels only slightly touch the rubber-elastic rail, it is destroyed over time, especially by locomotives or entire trains. In addition, the procurement and installation of such additional rubber-elastic rails is expensive.

Für abzubremsende Eisenbahnwagen, deren Ablaufgeschwindigkeit grösser als 2 bis 3m/s ist, werden gemäss der AT-PS 337 246 Bremsbalken vorgeschlagen, die mit seitlich verstifteten und angeschraubten Bremssegmenten ausgestattet sind. Die Segmente sind mit gegenseitigem Abstand nebeneinander an inneren Längsseiten der Bremsbalken mittels horizontaler Schraubbolzen und Spannstiften befestigt, die auch die Anpress- und Bremskräfte aufnehmen. Mit solchen Segmenten kann die Lärmentwicklung weitgehend unterdrückt werden, weil infolge der Reibung zwischen den Bremsbalken und der Radbandage des abzubremsenden Wagens beim Bremsvorgang lediglich die an den Anpressflächen des Bremsbalkens befestigten Segmente zu Eigenschwingungen angeregt werden.For railway cars to be braked, the running speed of which is greater than 2 to 3 m / s, according to AT-PS 337 246 brake bars are proposed which are equipped with brake pins that are pinned on the side and screwed on. The segments are attached to one another at a mutual distance from one another on the inner longitudinal sides of the brake beams by means of horizontal screw bolts and dowel pins, which also absorb the contact and braking forces. With such segments, the noise development can be largely suppressed because, due to the friction between the brake beams and the wheel bandage of the car to be braked during braking, only the segments attached to the contact surfaces of the brake beam are excited to vibrate naturally.

Der Nachteil solcher mit seitlich angebrachten Segmenten-versehenen Bremsbalken besteht darin, dass bei Ablaufgeschwindigkeiten, die unter 2 bis 3m/s liegen, das Quietschgeräusch wieder ähnlich intensiv wie bei unsegmentierten Bremsbalken auftritt. Die Montage und Demontage der Segmente von der Seite ist durch Platzmangel erschwert.The disadvantage of such brake bars provided with laterally attached segments is that the squeaking noise occurs again at intensities that are below 2 to 3 m / s at a similar intensity to that of unsegmented brake bars. The assembly and disassembly of the segments from the side is space lack complicates.

Es ist die Aufgabe der Erfindung, eine Balkengleisbremse zu schaffen, mit welcher die gewünschte Lärmreduktion beim Bremsen von ablaufenden Eisenbahnwagen auch im niedrigen Geschwindigkeitsbereich erzielt wird. Die Balkengleisbremse soll so konstruiert werden, dass eine rasche und mühelose Auswechslung der Bremsbeläge möglich ist.It is the object of the invention to provide a bar track brake with which the desired noise reduction when braking railway wagons running is achieved even in the low speed range. The bar track brake should be designed so that the brake pads can be replaced quickly and effortlessly.

Diese Aufgaben werden erfindungsgemäss bei der eingangs genannten Balkengleisbremse auf solche Weise gelöst, dass die Bodenfläche jeder Aussparung, die in horizontaler Ebene liegt, breiter ist als die Aussparungshöhe und dass die Aussparungen voneinander durch quer zu den Längsachsen der Balken verlaufende Stege getrennt sind, in welchen Aussparungen die Segmente ortsfest eingebaut sind.According to the invention, these objects are achieved in the beam track brake mentioned at the outset in such a way that the floor area of each cutout, which lies in the horizontal plane, is wider than the cutout height and that the cutouts are separated from one another by webs running transversely to the longitudinal axes of the beams, in which Recesses the segments are installed in a fixed position.

Mit Vorteil sind die Segmente in den Aussparungen durch senkrecht verlaufende Schraubenbolzen festgehalten, wobei sich die Seitenflächen der Segmente gegen die Stege abstützen und die eigentliche Bremsflächen bildenden Längsflächen der Segmente frei liegen und die inneren Längsränder der Balken überragen.The segments are advantageously held in the recesses by vertically running bolts, the side surfaces of the segments being supported against the webs and the longitudinal surfaces of the segments forming the actual braking surfaces being exposed and projecting beyond the inner longitudinal edges of the beams.

Der Erfindungsgegenstand wird nachstehend anhand der Zeichnung beispielsweise näher erläutert. Es zeigen

  • Fig. 1 eine schematische Ansicht eines äusseren Balkenstückes mit Segmenten einer Balkengleisbremse und
  • Fig. 2 einen Querschnitt durch das eine Balkenpaar der Gleisbremse nach der Fig. 1 mit einem in strichpunktierter Linie angedeuteten Wagenrad.
The subject matter of the invention is explained in more detail below with reference to the drawing, for example. Show it
  • Fig. 1 is a schematic view of an outer bar section with segments of a bar track brake and
  • Fig. 2 shows a cross section through the one pair of bars of the track brake according to FIG. 1 with a carriage wheel indicated in dash-dotted line.

Aus der Fig. 2 ist ersichtlich, dass beidseitig einer Fahrschiene 7 je ein zu der Fahrschiene 7 parallel verlaufender Balken 1 einer Gleisbremse angeordnet ist. Je ein Balken eines zweiten, nicht dargestellten Balkenpaares der Gleisbremse ist in gleicher Weise beidseitig der zweiten Fahrschiene angeordnet. Bei einer einseitigen Balkengleisbremse wird nur ein Balkenpaar an einer Fahrschiene verwendet. Die Bremsbeläge der Balken 1 bestehen, wie aus den Fig. 1 und 2 ersichtlich ist, aus Segmenten 8 oder 12, die zwischen sich eine für abzubremsende, auf der Fahrschiene 7 laufende Räder 6 (siehe die Fig. 2) eines Eisenbahnwagens bestimmte Bremsrille bilden.From FIG. 2 it can be seen that a bar 1 of a track brake running parallel to the running rail 7 is arranged on both sides of a running rail 7. One each Bars of a second pair of bars, not shown, of the track brake are arranged in the same way on both sides of the second rail. With a one-sided Bar track brake, only one pair of bars is used on one rail. The brake pads of the beams 1, as can be seen from FIGS. 1 and 2, consist of segments 8 or 12 which form between them a brake groove intended for braked wheels 6 running on the rail 7 (see FIG. 2) of a railroad car .

Wie aus der Fig. 1 weiter zu entnehmen ist, ist die innere Längsseite jedes Balkens 1 mit nach oben offenen Aussparungen 2 versehen, die durch quer zur Längsachse des Balkens 1 verlaufende Stege 3 voneinander getrennt sind. Die Länge dieser Aussparungen 2 beträgt mit Vorteil etwa 650 - 700 mm. In diesen Aussparungen 2 sind die Segmente 8, 12 so eingesetzt, dass sie sich mit ihren Endflächen gegen die Stege 3 abstützen. Die Segmente 8, 12 sind in den Aussparungen 2 durch senkrecht verlaufende Schraubenbolzen 5 festgehalten. Mit 4 sind die Löcher für Schraubenbolzen 5 in den Aussparungen 2 und mit 13 die Löcher für nicht dargestellte Schraubenbolzen bezeichnet, mittels welcher der Balken 1 an nicht dargestelltem Tragaggregat befestigt ist.As can also be seen from FIG. 1, the inner longitudinal side of each beam 1 is provided with cutouts 2 which are open at the top and which are separated from one another by webs 3 running transversely to the longitudinal axis of the beam 1. The length of these recesses 2 is advantageously about 650-700 mm. The segments 8, 12 are inserted into these recesses 2 in such a way that their end faces are supported against the webs 3. The segments 8, 12 are held in the recesses 2 by vertical bolts 5. 4 with holes for bolts 5 in the recesses 2 and 13 with holes for bolts, not shown, by means of which the beam 1 is fastened to the support unit, not shown.

Mit Vorteil sind die Segmente 8 mindestens auf den äusseren Balken 1 der Balkenpaare als Sandwichsegmente ausgeführt, d.h. dass sie aus horizontal verlaufenden, aufeinander liegenden Schichten 9, 11, lO bestehen. Die schmalen Längsseiten dieser Schichten bilden die eigentlichen Bremsflächen; beim Anpressen des Balkens gegen die Räder stützen sie sich gegen die Radbandagen ab, wie aus der Fig. 2 ersichtlich ist. Die einzelnen Schichten der Segmente 8 können z. B. aus einem aus Stahl bestehenden Oberteil 9, einem ebenfalls aus Stahl bestehenden Unterteil 10 und einer Einlage 11 bestehen, die zwischen dem Oberteil 9 und dem Unterteil 10 liegt. Diese Einlage kann z. B. aus Kunststoff, Eisen, Eisenlegierungen, Nicht-Eisenmetallen, Sintermetallen, Keramik oder einem organischen Werkstoff, z. B. Holz, sein. Es ist aber auch möglich, die Materialien beliebig zu kombinieren und sie in beliebigen Schichten 9, 11, 10 zu verwenden. Die Segmente auf dem.inneren Balken 1 jedes Balkenpaares sind vorzugsweise als einstückige Vollsegmente 12 ausgebildet. Das Material dieser Vollsegmente kann das gleiche wie bei den Segmenten auf den äusseren Balken sein. Die Materialien können auch hier beliebig kombiniert werden. Die Bremse kann derart ausgeführt werden, dass vorwiegend die Segmente der inneren Balken die Aufgabe der Bremsung übernehmen und die Segmente der äusseren Balken nur den Gegendruck ohne massgebende Bremswirkung erzeugen. Dabei werden die Segmente der äusseren Balken mit Hilfe eines Schmiermittels gleitfähig gehalten. Es ist aber auch möglich, dass sowohl auf den äusseren als auch auf den inneren Balken die Segmente in Sandwichform oder als einstückige Vollsegmente ausgeführt werden.The segments 8 are advantageously designed as sandwich segments at least on the outer beams 1 of the pairs of beams, ie they consist of horizontally extending layers 9, 11, 10. The narrow long sides of these layers form the actual braking surfaces; when the beam is pressed against the wheels, they are supported against the wheel bandages, as can be seen from FIG. 2. The individual layers of the segments 8 can, for. B. from a steel part 9, a steel part 10 and an insert 11th exist, which lies between the upper part 9 and the lower part 10. This deposit can, for. B. made of plastic, iron, iron alloys, non-ferrous metals, sintered metals, ceramics or an organic material, for. B. wood. However, it is also possible to combine the materials as desired and to use them in any layers 9, 11, 10. The segments on the inner bar 1 of each pair of bars are preferably designed as one-piece full segments 12. The material of these full segments can be the same as for the segments on the outer bars. The materials can also be combined here as desired. The brake can be designed in such a way that predominantly the segments of the inner bars take over the braking function and the segments of the outer bars only generate the counter pressure without a significant braking effect. The segments of the outer beams are kept lubricated with the help of a lubricant. However, it is also possible for the segments to be designed in sandwich form or as one-piece full segments on both the outer and the inner beams.

Die Segmente 8, 12 sind formschlüssig in die Längsseiten der Balken 1 eingebaut, so dass die beim Bremsen auftretenden Kräfte direkt von den Balken aufgenommen und auf das Tragaggregat übertragen werden. Somit können auch nicht metallische Segmentwerkstoffe sowie Sandwichsegmente verwendet werden. Die Schraubenbolzen 5 haben primär eine Haltefunktion, nehmen aber keine Anpresskräfte und nur geringe Bremskräfte auf.The segments 8, 12 are installed in a form-fitting manner in the longitudinal sides of the bars 1, so that the forces occurring during braking are absorbed directly by the bars and transmitted to the supporting unit. This means that non-metallic segment materials and sandwich segments can also be used. The bolts 5 primarily have a holding function, but do not take up any contact forces and only slight braking forces.

Die Segmente können an beiden Längsseiten je um etwa 10 mm abgenutzt werden, wobei der jeweilige Abnutzungsstand durch eine visuelle Kontrolle sofort feststellbar ist. Eine Nachmessung mit einem Messinstrument erübrigt sich. Dank der Befestigung der Schraubenbolzen 5 von oben ist eine rationelle Kontrolle derselben und die Auswechslung der Segmente 8, 12 gewährleistet. Dies wirkt sich im Sinne vereinfachten Unterhaltes aus.The segments can be worn by about 10 mm on each of the long sides, and the respective level of wear can be determined immediately by visual inspection. A final measurement with a measuring instrument is unnecessary. Thanks to the fastening of the screw bolts 5 from above, a rational control of the same and the replacement of the segments 8, 12 is ensured. This has an impact on simplified maintenance.

Die oben beschriebene Anordnung der Segmente an den Bremsbalken bringt eine sehr deutliche Minderung sowohl der Häufigkeit als auch der durchschnittlichen Intensität der Quietschgeräusche beim Bremsen der ablaufenden Eisenbahnwagen. Die Reduktion beträgt 10 bis 15 dB(A). Die Quietschgeräusche treten bis zu 30 Mal weniger häufig auf als bei den Bremsbalken nach der AT-PS 337 246.The arrangement of the segments on the brake beams described above brings a very significant reduction in both the frequency and the average intensity of the squeaking noises when braking the running railroad cars. The reduction is 10 to 15 dB (A). The squeaking noises occur up to 30 times less frequently than with the brake beams according to AT-PS 337 246.
